  • Shaft packing
    Patent number: 5544895
    Abstract: A shaft packing includes a casing and at least two polymeric disks. One disk forms a protective lip and the other disk forms a packing lip. The internal diameters of the disks are smaller than the external diameter of the shaft to be packed. Between the two disks is positioned an expanding ring which ensures an inversion and expanding of the packing lip in the opposite direction to the protective lip.
